Compile Time vs Run Time | Simply Explained
Blog / Compile Time vs Run Time | Simply Explained
So what actually is the difference between compile time and run time?TL;DR Summary Compile Time At compile time, the input is your source code – the code you wrote, plus any additional files like libraries or headers that your code needs to work.The compiler (a special program) takes your source code and translates it into machine code (something the computer can understand and execute).If everything goes well, the output is usually an executable program (something you can run), or object code (which might need further linking). If there are errors, you get error messages instead.Compile time errors include: Run Time Run time refers to the period during which a program is executed. This is when the compiled code is loaded into memory and run on the CPU.The program performs the tasks defined in the code, including processing input, manipulating data, and producing output.Run time errors include:
- A CPU (Central Processing Unit) is the primary component of a computer that handles all types of computing tasks required for the operating system and applications to run and it tries to do so with minimal latency and is often referred to as the brains of a computer.
- GPU (Graphics Processing Units) as the name suggests was was originally invented to help render images on display devices.
Don't let one question ruin your next technical interview...
- Syntax Errors: These are mistakes in your code's structure. For example, missing a semicolon or using the wrong brackets.
- Typechecking Errors: These occur when you try to use data in a way that doesn’t make sense, like adding a number to a string without proper conversion.
- Logic Errors: Bugs in the code that produce incorrect results.
- Exception Handling: Issues such as divide-by-zero errors, null pointer dereferences, and out-of-bounds array access.
- Resource Errors: Problems like memory leaks, file not found, or network issues.
